I can't understand why they making swap from NEP5 to ERC tokens? As far as I know they were going to make own blockchain.. so why this swap? And when will be launched own blockchain? Where is gone roadmap from the site? I can't find...
And why price pumping today? Only because of this swap?

the swap is to allow the token to be easily added to other exchanges. because most exchanges hate how the Neo side tokens works. and wont implement it.
so by switching to Erc20 tokens, it will allow easy access to bigger exchanges before the main net release in june.
overall its a good move, only if we do get on more exchanges, a lot more people would know and buy NKN if we were trading on Binance or Bithumb or any of the big ones.
Erc20 swap Greatly increases the chance of this happening
